I believe prince sells enough lower end stuff like tweener and beginner frames, cheaper stuff (stuff you find at big five and chain outlet stores) to make up for any gaps at the top of performance racquets.
But for me, when I think of prince one thing comes to mind, chick sticks. I honestly don't think of david ferrer, gael monfils or victor troicki. For me it's always been the bryan bros. and female players.
Their cosmetics also need to change. There was one stick that came out a year ago where there were just a bunch of random squiggles, basically a vector mesh that was shifted and all the points were rearranged. For me, this is unacceptable, that was a prototype design and should not have made it into production. Honestly, it was intern work that got passed into output which is pretty sad that someone actually approved of it. The art director should be fired for that, because that design is what you see in graphic design 101 students who have no ideas who just mess around with vector meshes, the same way when someone who doesn't know design principles uses photoshop filters as a substitute. At design school someone who submitted that to one of my professors would have had to redraft a new design and would have been laughed at for trying turning in crap at the last minute trying to pass it off like they actually tried.
So besides the cosmetics (which most of all the racquets have a pretty sad ailment of bland and boring designs that repeat themselves) the other thing I have an issue with is every *update* seems to be nothing more than just a new paintjob and since the paintjob sucks to begin with the updates seem to suffer from a cycle of bad cosmetics without any type of technology applied. They don't even try to hide the fact that they didn't try to work on new technology, regardless if it's fake or not, but the only thing I see is the same borrowed technology of the portholes on the sides. Whether or not head's IG of D30 work or not it does accomplish a few things. It really encourages buying power and excites the market, and it does in fact change the feel and performance of the previous line that it says it updates. Going back to prince now, all the racquets no matter performance, tour, tweener all feel and play alike. When an update does come out nobody every gets excited because there is no difference in the current and the succeeding frame. They also don't address any issues that people seem to have issues with which one for instance is a lack of feel.
Prince reminds me of Waltham/Elgin pocketwatches trying to make new pocket watches in a day where their competitors are trying new things and have moved on and ahead of them.
Prince has to only ask itself only one thing. Whenever a new prince line (yonex should be listening too) comes out, nobody is ever really excited about it as people seem to be with Head, Wilson or Babolat. Lastly I really wish Prince would try to offer frames that are drastically different from one and another. Generally most prince frames seem to play the same and that's not much feel.
I think prince has some good nostalgia like the POG, but for me it suffers from Dana Carvey syndrome in that when it got really big at the height of its career, it all of a sudden stopped trying and continued to fade into oblivion.
